pH
7.2 to 7.6
How acidic or basic the water is. E.W.A. reads it so you know at a glance whether the water is comfortable and whether your sanitizer can work.
How it works
Perfect water, in under an hour.
E.W.A. is a small sensor that fits inline on the spa or pool you already have, plus an app that reads the water in plain words. No adapters, no rebuild. Fit it, power it, pair it, and it starts reading.
What E.W.A. is
E.W.A. is two things: a small sensor that fits inline on your existing spa or pool plumbing, and an app that tells you what the water needs. The sensor sits in the water flow you already have and reads pH, sanitizer and temperature. There are no adapters to source and nothing to rebuild.
Because it reads the water itself and not your equipment, it fits any spa and any pool. You do not change how you run your spa. You just get a clear, constant read on the water and a plain instruction when something needs adding.
Install in under an hour
Four steps, no special tools, no plumber. Here is the whole install from box to first reading.
- Fit the sensor inline. Fit E.W.A. inline on your existing spa or pool plumbing. It sits in the water flow you already have, so there are no adapters to source and nothing to rebuild.
- Power it. Power it one of two ways: run it standalone on 220V, or connect it to a Balboa BP pack or a Gecko in.YE/YT pack (V2 or V3) if you have one.
- Pair it in the app. Open the app and pair the sensor over Bluetooth, then connect it to your WiFi. This takes a couple of minutes and links the sensor to your account.
- Done, it starts reading. That is it. E.W.A. starts reading pH, sanitizer and temperature and shows you the water in plain words.
What it watches
E.W.A. reads three numbers every ten minutes, that is 144 readings a day, the same way every time. No strips, no squinting at colours.
Sanitizer
650 to 750 mV ORP
The real killing power of the water, measured as ORP in millivolts. A number in ppm can look fine while the water is unsafe. ORP reads what actually keeps you safe.
Temperature
Steady
Comfort, running cost and sanitizer speed all ride on temperature. A sudden drift is an early sign of a heater or flow problem.
The app reads like a person
The numbers are only useful if you know what to do with them. So E.W.A. does that part for you. It names the problem in plain words and tells you the exact dose to add, for example add pH-up when the water turns acidic, or shock the sanitizer when the killing power falls.
You are never left holding a reading and guessing which bottle to reach for. If you want the chemistry behind those numbers, the ideal ranges and what each one means, read the water balance guide.
Install questions
Is E.W.A. hard to install?
No. It fits inline on the plumbing you already have, so most people are done in under an hour. There are no adapters to buy and nothing to rebuild. If you can connect a hose fitting, you can fit E.W.A.
Does it need WiFi?
For remote readings, yes. E.W.A. pairs over Bluetooth and sends its readings to the app over your WiFi, so it needs WiFi within reach of the spa or pool. Once paired, it keeps reading and sending on its own.
Indoor or outdoor?
Both. E.W.A. is built for outdoor spa and pool, and it works indoors just as well. It reads the water itself, not the room, so the setting does not change how it works.
Which spas and pools does it fit?
Any spa and any pool. E.W.A. reads the water, not your equipment, so it is not tied to a particular brand of spa or pool. It fits inline on standard plumbing.
How is it powered?
Two ways. It runs standalone on 220V, or it connects to a Balboa BP pack or a Gecko in.YE/YT pack (V2 or V3) if your spa already has one. You pick whichever suits your setup.
Fit it once, stop guessing.
E.W.A. reads pH, sanitizer and temperature in real time and tells you exactly what to add. Simply perfect water, every time.
